About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1548920370. Listed at 8 retailers as of November 6, 2026, with prices from £2,678 to £5,130, a £2,453 spread on the same certified stone. With Clarity lists it at £5,130. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
